The Future of Natural Language Queries: Simplifying Integration with Espressif's OpenAI Component for implementing ChatGPT

The digital age has ushered in a plethora of technological advancements, and one of the most sought-after features is the ability to interact with devices using natural language queries.

ChatGPT, for instance, has revolutionised the way we communicate with machines. However, the implementation of such sophisticated systems can be daunting, especially for electronic engineers who are constantly on the lookout for streamlined solutions.

Enter Espressif's new 'OpenAI Component' library. This innovative tool is designed to simplify the integration process, making it easier than ever for engineers to incorporate the convenience of natural language queries into their projects.

Introducing the OpenAI Component

Espressif has introduced a powerful ESP-IDF component to provide developers with comprehensive coverage of OpenAI API features. This component is not just a simple tool; it offers extensive support, focusing on a broad spectrum of functionalities.

However, it's worth noting that file operations and fine-tuning capabilities are excluded. To aid developers in their journey, comprehensive documentation is readily available, ensuring that the APIs are understood with ease.

Getting Started with the OpenAI Component

Instantiation and API Key Acquisition:

  • Begin by instantiating an object and providing a secure “API key” as a parameter.

  • This OpenAI key can be obtained from the OPENAI website. To utilise OpenAI services, one must first register an account, purchase tokens, and then secure their unique API key.

Utilising the Chat Completion API:

  • After creating the OpenAI object, the next step is to call the chatCompletion API.

  • Set the necessary parameters, send a message (indicating it's not the concluding message), and then retrieve the generated response for further use or processing.

openai = OpenAICreate(key);
chatCompletion = openai->chatCreate(openai);
chatCompletion->setModel(chatCompletion, "gpt-3.5-turbo");
chatCompletion->setSystem(chatCompletion, "Code geek");
chatCompletion->setMaxTokens(chatCompletion, CONFIG_MAX_TOKEN);
chatCompletion->setTemperature(chatCompletion, 0.2);
chatCompletion->setStop(chatCompletion, "\r");
chatCompletion->setPresencePenalty(chatCompletion, 0);
chatCompletion->setFrequencyPenalty(chatCompletion, 0);
chatCompletion->setUser(chatCompletion, "OpenAI-ESP32");
OpenAI_StringResponse_t *result = chatCompletion->message(chatCompletion, "Hello!, World", false);
char *response = result->getData(result, 0);

Leveraging the Audio Transcription API:

  • Similarly, after creating the OpenAI object, you can call the audioTranscriptionCreate API.

  • Set the required parameters, such as the audio file and language, and then initiate the audio transcription process. Once done, the transcription result can be retrieved for further use or processing.

audioTranscription = openai->audioTranscriptionCreate(openai);
audioTranscription->setResponseFormat(audioTranscription, OPENAI_AUDIO_RESPONSE_FORMAT_JSON);
audioTranscription->setLanguage(audioTranscription, "en");
audioTranscription->setTemperature(audioTranscription, 0.2);
char *text = audioTranscription->file(audioTranscription, (uint8_t *)audio, audio_len, OPENAI_AUDIO_INPUT_FORMAT_WAV);

ESP-BOX ChatGPT Demo Example: A Glimpse into Real-World Implementation

One of the most exciting showcases of Espressif's OpenAI Component is the ESP-BOX ChatGPT Demo. This demonstration provides a tangible example of how seamlessly the OpenAI Component can be integrated into real-world applications.
